EMERY GRAVES, OF SYRACUSE, NEW YORK.

NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented June 10, 1913.

Application filed March 26, 1913. Serial No. 757,026.

To all whom it may concern Be it known that I, EMEBY GRAVES, a citizenof the United States, residing at Syracuse, in the county of Onondagaand State of New York, have invented certain new and useful Improvementsin Non- Refillable Bottles; and I do hereby declare the following to bea full, clear, and eXact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to non-refillable bottles, having particularreference to that type of such devices in which a ball check valve isemployed.

As its principal object this invention contemplates the provision of anon-refillable bottle in which simple but effective means are providedfor preventing the tampering with the ball valve in the endeavor torefill the bottle.

A further object of this invention is to construct the bottle and valveapparatus therefor with such regard to proportion, number andarrangement of parts that the device may be cheaply manufactured, andwill be efficacious and durable in its operation.

The above and additional objects are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification and then more particularly pointed out in the claim whichis appended hereto and forms a part of this application.

\Vith reference to the drawings, wherein I have illustrated thepreferred embodiment of my invention as it is reduced to practice, andthroughout the several views of which similar reference numeralsdesignate corresponding parts:

Figure 1 is a longitudinal section taken approximately central of thebottle. Fig. 2 is an elevation taken on the plane face of one of the twoplanoconvex members arranged in the upper portion of the bottle neck.Fig. 3 is a section on line 3-3 of Fig. 1; and Fig. 4 is a detail viewof a locking spring.

Proceeding now to the description of the drawings, the preferredembodiment of my invention includes a bottle 1 of the customarystructure, from the breast 2 of which extends a neck 3. The neck of thebottle is blown to produce an annular groove adjacent its mouth toprovide a seat for a cork washer 4-. Adjacent its lower end the bottleneck 3 is equipped with an inwardly projecting annular shelf 5 arrangedto support a cored casting 6 which may be made of porcelain or any othersuitable plastic or metal substance. The casting 6 is substantiallycylindrical and carries an integrally formed boss 7 projecting from itslower end. The member 6 is cored as at 7 to produce an escape openingfor the fluid and is adapted to receive in the chamber 7 a ball valve 8.The chamber 7 is substantially frustoconical and is formed with thesmaller end at the lower portion of the casting, being arranged to serveas a valve seat for the ball 8. An opening 9 communicates with theopening 7 for an obvious purpose. A cork washer 10 may be interposedbetween the member 6 and the shelf 5 to prevent leakage of the liquid.

Mounted on the upper portion of the casting 6 are a pair ofsemicylindrical cored castings one of which is illustrated in detail inFig. 2 and designated as an entirety by the numeral 11. Each of themembers 11 is cored to produce a serpentine fluid passage 12,communicant at its upper terminal with a cylindrical chamber 13, thewall. of which is perforated as at 14: to permit the liquid to issuefrom the casting when the apparatus is arranged for dispensing of theliquid. The members 11 are similar in structure being thus formed toadapt the passages 12 and chambers 14: to registration when the twocastings are in assembled position in the bottle neck. Intermediate thelength of these members 18 is attached a substantially L-shaped spring15 seated in a suitable recess formed in the castings and provided witha vertical leg inclined outwardly from the castings for a purpose to behereinafter disclosed. At a point below the washer 4 the neck of thebottle is provided with an annular recess 16, formed to produce anannular shoulder 1.7 and the inwardly inclined annular wall 18. It willbe apparent upon reference to Fig. 1 that the vertical legs of thespring 15 are arr. nged for sliding movement on the walls 18 of therecess 16 and are adapted upon upward movement of the castings 11 toengage the shoulder 17, thus being effectively guarded against anyattempts to withdraw these castings from the bottle neck. The upper endof the castings is provided with a common worm bore 9 adapted to receivea hook or similar instrument as will be disclosed hereinafter.

Supplemental to the above'disclosures regarding the construction of thesemicylindrical castings 11, it is desirable to emphasize the fact thatwhile I have illustrated the cylindrical member of the bottle as beingformed in two sections, and have described them in that manner, it maynevertheless be readily cast in one piece. It is also to be observedthat this invention anticipates the formation of these members 11 in onepiece, but it has been found desirable to illustrate and describe themechanism referred to as consisting of two equal parts, in that thismethod of illustration and description is more comprehensive andexplanatory.

The actual construction of the body being thus disclosed, it now remainsto describe the operation of the device, and to enumerate the manyadvantages resultant from the peculiar construction of this device.

Briefly, the operation is as follows: In

' assembling the parts the washer 10 is disposed on the shelf 5 and thecasting 6 is then placed within the neck with the boss portionprojecting below the shelf 5 and with the main body portion of themember 6 on the washer 10. The ball 8 is then placed in the opening 7and the two semi-cylindrical castings 11 placed in the bottle neckresting in their assembled position on the upper portion of the member6. It will be seen that in placing the castings 11 in the bottle, thesprings 15 will expand and engage the wall 18 of the recess 16. In thesealed position of the castings 11, the openings 14 are sealed by thewasher 4, the top of the castings being disposed at a lower level thanthe top of the bottle, thus providing a chamber at the upper portion ofthe neck for the reception of a cork 20. When it is desired to dispensethe liquid from the bottle the cork 20 is removed and a hook or similarinstrument is inserted in the worm bore 19 by which means the castings11 are drawn upwardly to bring the top of the castings flush with thetop of the neck simultaneously withdrawing the openings 14: from sealedengagement with the washer 4:11 It will be seen that when the castings11 are drawn up into dispensing position," the spring 15 will engage theshoulder 17 thus preventing further withdrawal of the castings. Todispense the fluid it is only necessary to invert the bottle, thusunseating the ball 8 and allowing the passage of the fluid through theopenings 9, the passage 7, and the perforations 14:. It is desirable toemphasize the fact that by. the provision of the serpentine fluidpassage 12, all possibility of illicit tampering with the ball valve 8is eliminated. It is also to be observed that the liquid in issuingfro-m the bottle cannot come in contact with the spring 15 which maytherefore be made of steel or other equally effective and durablematerial.

In reduction to practice, I have found that the form of my invention,illustrated in the drawings and referred to in the above description, asthe preferred embodiment, is the most practical; yet realizing that theconditions concurrent with the adoption of my device will necessarilyvary, I desire to emphasize the fact that various minor changes indetails of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages ofmy invention, as defined in the appended claim.

WVhat is claimed is:

The combination with a liquid receptacle having a dispensing neck, of anannular shelf formed interiorly of said neck adjacent its lowerterminal, a valve seat mounted on said shelf, a valve arranged in saidvalve seat, a cored cylinder arranged within said bottle neck andadjacent the said valve seat, said cylinder being provided with aserpentine fluid passage communicating at its lower terminal with thesaid valve seat, and at its upper terminal with a plurality ofperforations formed in the wall of the cylinder and adjacent the upperend thereof, an annular shoulder formed interiorly of the said bottleneck, a plurality of leaf springs carried by the said cylinder andadapted to engage the said shoulders in open position of the saidcylinder, a sealing washer mount ed interiorly of the said neck andadapted to seal the said perforations of the said cylinder in the closedposition of said cylinder, said cylinder being adapted to be drawnupwardly to bring the said perforations out of engagement with the saidlast-mentioned portion.

In testimony whereof I aflix my signature in presence of two witnesses.
